One of many massive “gotchas” the anti-EV crowd tries to throw at EVs is that they’d fail you in a hurricane evacuation. I’ve lined this earlier than, repeatedly, however regardless of what number of occasions we bust the myths and rubbish surrounding it, the lie simply doesn’t go away. Like different right-wing memes in Florida, it’s even managed to develop into a invoice within the legislature.
For individuals who received’t learn the hyperlinks, I’ll shortly sum up why this “checkmate, libs” trash argument is unsuitable. Take into account that fuel pumps require electrical energy to get the fuel from the underground storage tanks, leaving fuel vehicles and EVs on degree floor. However, when fuel pumps can run out of gasoline as a result of demand, the EV charging stations preserve chugging alongside proper up till the ability goes out (and that’s properly past evacuation time). Plus, most EVs get charged at house and may evacuate far sufficient to get to security on what’s already of their battery pack each morning. Lastly, EVs don’t lose vary sitting in evacuation visitors jams as unhealthy as gas-powered vehicles do.
So, sure, EVs are ok to not less than get inland far sufficient for security, even with present infrastructure, however that doesn’t imply the scenario can’t be improved upon to make evacuations simpler for the households that personal EVs after they’ve made the minimal distance for security.
The issue I’m about to debate (and counsel critical options for) isn’t one thing that impacts many individuals at the moment, but when we wish to swap out most fuel automobiles for EVs, finally we may discover half the refugee inhabitants on this place, so it’s one thing we’d higher take into consideration now as an alternative of as soon as we’re in the midst of a giant drawback.
The Downside That Stays
For EVs, we don’t want almost as many charging stations as fuel stations. As a result of most of us cost at house, most of us solely want public charging on days the place we do an uncommon quantity of driving. We are going to want many extra EV charging stations because the inhabitants of EV drivers grows, but it surely doesn’t make sense to construct many extra charging stations than future EV drivers will really want. Like something within the financial system, we’ve got to be environment friendly with our greenbacks.
Fuel stations have an analogous financial effectivity. There are sufficient fuel stations to satisfy the excessive finish of regular demand, however even in regular occasions you continue to see lots of people in line at locations like Sam’s Membership and Costco. There’s sufficient gasoline manufacturing to satisfy regular wants, and sufficient tanker vans obtainable to haul gasoline to stations on the charge of regular wants. However, earlier than hurricanes, we’ve seen fuel stations run out of gasoline earlier than some individuals acquired an opportunity to evacuate, so there’s simply not sufficient spare capability within the gasoline trade to fulfill extraordinary demand.
With gasoline, wiser individuals advocate that drivers replenish at half a tank and preserve the underside half in reserve for emergencies. That is most likely sufficient to get far sufficient from the evacuation zone to fan out a bit and keep away from overwhelming the fuel provide as badly as they did within the place being evacuated.
With EVs, the issue of what occurs a battery’s price of vary from hazard isn’t as simple to unravel. As a result of there’s even much less spare charging capability, and the entire individuals who usually have to cost at house immediately want to make use of public chargers, there might be some fairly horrific bottlenecks as increasingly individuals drive EVs.
Now, to be completely clear, for many EVs there’s sufficient vary to be out of mortal hazard earlier than this turns into an issue. However, having an enormous variety of drivers dealing with days-long charging strains goes to nonetheless current a smaller humanitarian disaster if we don’t make some plans to assist alleviate the issue.
Some Concepts To Present Surge Charging Capability For Evacuations
The position of federal authorities (together with FEMA, but additionally the Division of Protection and others) is to help state and native governments in coping with catastrophe. There are additionally state-to-state and worldwide preparations for help that simplify and expedite the rendering of help. With a catastrophe that we will see probably coming (like a hurricane), it’s common in any respect to pre-position sources and help employees that may predictably be wanted.
As a result of EV charging infrastructure is not going to be as much as the duty, it makes heaps of sense to have some further capability that may be moved round and put within the line of an anticipated evacuation.
The apparent approach to do that is one thing we already see Tesla do when it anticipates vacation weekends and different occasions overwhelming the Supercharger community:

Tesla’s resolution includes a literal truckload of charging stations and batteries getting dropped off to supply further stalls for drivers. It will make sense for FEMA to be in contact with Tesla to assist present data on the place these chargers might be wanted and to supply some federal grants to construct extra of them and have them on standby. The one factor I’d change for federally-funded cell Superchargers is that they need to have Magic Dock put in to serve extra EV drivers.
FreeWire’s charging stations with built-in battery packs are one other good resolution to this. As an alternative of putting in these on vans, they might be loaded on freight pallets, and even shipped round as lower than load (LTL) freight for extra flexibility. If FEMA officers and their state counterparts may work with companies and authorities properties to have energy able to obtain Freewire stations on pallets, they might be shortly related and introduced on-line forward of a potential evacuation. It might be a good suggestion to even have some moveable photo voltaic arrays or mills to cost up FreeWire stations in areas that might lose energy.
One other option to open up surge capability within the EV charging community could be to enlist the assistance of automotive sellers. Many automotive sellers have EV charging stations on their tons, however the tons are closed at night time. Authorities officers ought to work now to develop plans with these sellers to maintain these stations open 24 hours on a brief foundation. This will contain placing cops on the lot to maintain sellers snug with individuals being there once they’re closed, or serving to sellers make a greater fence to solely open the a part of the lot the place the station is.
We additionally shouldn’t overlook the position of Degree 2 charging in serving to alleviate Degree 3/DCFC bottlenecks. Authorities amenities and companies may open their tons to refugees who want a cost, and let individuals sleep of their automobiles to get sufficient cost to get to wherever that they had deliberate to evacuate to.
RV parks are one other useful resource that’s largely prepared to supply energy by way of 50-amp service, however preparations will have to be made to have moveable EVSEs positioned at taking part RV parks forward of time, together with devoted areas for individuals who introduced their very own twine units. It might even be a good suggestion for officers to drop moveable shelters, like Shiftpods or Hexayurts (you see these at Burning Man and different festivals) with cots and sleeping baggage. This might give EV drivers and their households a spot to sleep whereas they cost in a single day, and the RV park homeowners may nonetheless cost their regular charges for the RV house.
Lastly, this all requires some training and public outreach. Putting in further charging capability is ineffective if drivers don’t know the place to search out the non permanent stations, Degree 2 stations opened up briefly, and RV parks able to put them in a shelter for the night time. It will be a good suggestion to place out press releases, have an internet site with data, and put the stations up on apps like Plugshare. It may be a easy as having any person with pamphlets go to overwhelmed chargers with data on these pop-up options and the best way to get to them.
Lastly, the EV group, sellers, and producers ought to coach individuals on the best way to be ready for an evacuation. For instance, I do know some drivers prefer to cost up as soon as per week at house solely when their automotive is low, however it will be higher for them to cost as much as 80-90% each night time to at all times have sufficient vary each morning to get out of hazard.
I’m Right here To Assist
If anyone at any degree of presidency or in a catastrophe non-profit has extra questions on planning to maintain EV drivers evacuating easily, be happy to succeed in out to me. You may e-mail CleanTechnica and so they’ll ahead it to me, or you’ll be able to discover me on Twitter. I’d be glad to assist!
